  • A Review of the Classification of Jurassic Aspidoceratid Ammonites – the Superfamily Aspidoceratoidea
    VOLUMINA JURASSICA, 2020, XVIII (1): 47–52 DOI: 10.7306/VJ.18.4 A review of the classification of Jurassic aspidoceratid ammonites – the Superfamily Aspidoceratoidea Horacio PARENT1, Günter SCHWEIGERT2, Armin SCHERZINGER3 Key words: Superfamily Aspidoceratoidea, Aspidoceratidae, Epipeltoceratinae emended, Peltoceratidae, Gregoryceratinae nov. subfam. Abstract. The aspidoceratid ammonites have been traditionally included in the superfamily Perisphinctoidea. However, the basis of this is unclear for they bear unique combinations of characters unknown in typical perisphinctoids: (1) the distinct laevaptychus, (2) stout shells with high growth rate of the whorl section area, (3) prominent ornamentation with tubercles, spines and strong growth lines running in parallel over strong ribs, (4) lack of constrictions, (5) short to very short bodychamber, and (6) sexual dimorphism characterized by minia- turized microconchs and small-sized macroconchs besides the larger ones, including changes of sex during ontogeny in many cases. Considering the uniqueness of these characters we propose herein to raise the family Aspidoceratidae to the rank of a superfamily Aspi- doceratoidea, ranging from the earliest Late Callovian to the Early Berriasian Jacobi Zone. The new superfamily includes two families, Aspidoceratidae (Aspidoceratinae, Euaspidoceratinae, Epipeltoceratinae and Hybonoticeratinae), and Peltoceratidae (Peltoceratinae and Gregoryceratinae nov. subfam.). The highly differentiated features of the aspidoceratoids indicate that their life-histories

Within the Chacay Group, the Lower to basal Upper Oxfordian La Manga Formation, below, mostly detrital and biogenic, and the Upper Oxfordian Au- quilco Formation, above, mainly chemical, are distinguished. The La Manga Formation (with Gryphaea calceola lumachelle) is rich in ammonite faunas, particularly of thc upper Cordatum to lower Canaliculatum Zones. In Neuquén and Mendoza provinces of Argentina, the Pli- catilis Zone or Middle Oxfordian has yielded Perísphinctes spp., Euaspidoceras spp., Aspido- ceras spp., together with Mayaítes (Araucanites ) stípanícfcí, M.

  • The Middle Oxfordian to Lowermost Kimmeridgian Ammonite
    Volumina Jurassica, 2010, Viii: 5–48 The Middle Oxfordian to lowermost Kimmeridgian ammonite succession at Mikhalenino (Kostroma District) of the Russian Platform, and its stratigraphical and palaeobiogeographical importance Ewa GŁOWNIAK1, Dmitry N. KISELEV2, Mikhail ROGOV3, Andrzej WIERZBOWSKI1, John K. WRIGHT4 Key words: ammonites, biostratigraphy, Boreal zonation, Subboreal zonation, Submediterranean zonation, correlation, Oxfordian/ Kimmeridgian boundary. Abstract. The Mikhalenino section on the Russian Platform has yielded numerous ammonites from the Middle and Upper Oxfordian and lowermost Kimmeridgian, collected bed by bed. The ammonites belong mostly to the Boreal family Cardioceratidae, but also to the Sub- boreal family Aulacostephanidae; additionally at some levels there were collected various Submediterranean ammonites (Perisphinctidae, Oppeliidae and Aspidoceratidae). The co-occurrence of ammonites representative of different faunal provinces makes possible recognition of the Boreal, Subboreal, and partly also Submediterranean standard zonations. In consequence, it is possible to make a close correlation between these zonal schemes. The Oxfordian/Kimmeridgian boundary at the Pseudocordata/Baylei zonal boundary of the Subboreal zonal scheme corresponds precisely to the Rosenkrantzi/Bauhini zonal boundary. This boundary of the stages defined well faunistically in the Flodigarry section (Isle of Skye, Scotland) and proposed as a candidate for the uniform Oxfordian/Kimmeridgian boundary, can be also recognized in the Russian sec- tion studied. The boundary can be traced in the Mikhalenino section using the same criteria as used at Staffin: the appearance of the first representatives of Pictonia [M]–Prorasenia [m] (Subboreal), and the first appearance of Amoeboceras (Plasmatites) (Boreal). This indi- cates the large correlation potential of the boundary defined in this way. The research on the Mikhalenino section has provided the new palaeontological findings described in this study.

Mitta Paleontological Institute, Russian Academy of Sciences, Profsoyuznaya 123, Moscow, 117997 Russia email: [email protected] Received April 21, 2010 Abstract—Ammonites from the Riasanites rjasanensis Zone (Ryazanian Stage of the Russian Platform) of the family Neocomitidae are considered. The new species Mazenoticeras robustum sp. nov. and M. ceccai sp. nov. are described. Other members of this genus and of the genera Malbosiceras and Pomeliceras are identified in open nomenclature. Keywords: ammonites, Neocomitidae, Mazenoticeras, Pomeliceras, Malbosiceras, Ryazanian Stage, Berria sian Stage, Russian platform.

  • The Upper Jurassic of Europe: Its Subdivision and Correlation
    The Upper Jurassic of Europe: its subdivision and correlation Arnold Zeiss In the last 40 years, the stratigraphy of the Upper Jurassic of Europe has received much atten- tion and considerable revision; much of the impetus behind this endeavour has stemmed from the work of the International Subcommission on Jurassic Stratigraphy. The Upper Jurassic Series consists of three stages, the Oxfordian, Kimmeridgian and Tithonian which are further subdivided into substages, zones and subzones, primarily on the basis of ammonites. Regional variations between the Mediterranean, Submediterranean and Subboreal provinces are discussed and correlation possibilities indicated. The durations of the Oxfordian, Kimmeridgian and Tithonian Stages are reported to have been 5.3, 3.4 and 6.5 Ma, respectively. This review of the present status of Upper Jurassic stratigraphy aids identification of a num- ber of problems of subdivision and definition of Upper Jurassic stages; in particular these include correlation of the base of the Kimmeridgian and the top of the Tithonian between Submediterranean and Subboreal Europe. Although still primarily based on ammonite stratigraphy, subdivision of the Upper Jurassic is increasingly being refined by the incorporation of other fossil groups; these include both megafossils, such as aptychi, belemnites, bivalves, gastropods, brachiopods, echino- derms, corals, sponges and vertebrates, and microfossils such as foraminifera, radiolaria, ciliata, ostracodes, dinoflagellates, calcareous nannofossils, charophyaceae, dasycladaceae, spores and pollen. Important future developments will depend on the detailed integration of these disparate biostratigraphic data and their precise combination with the abundant new data from sequence stratigraphy, utilising the high degree of stratigraphic resolution offered by certain groups of fos- sils.
